The impact of SFCL and SMES integration on the distance relay [PDF]
Physica C: Superconductivity and its Applications, 2016 Abstract The superconducting fault current limiter (SFCL) is an ideal short-circuit fault current limiting device that can limit the fault current without any delay and control the voltage drop of the non-fault line. The superconducting magnetic energy storage (SMES) device can exchange the active and reactive power independently, so it is applied ...

International Transactions on Electrical Energy Systems, Volume 2025, Issue 1, 2025.Accurate determination of critical clearing time (CCT) remains a fundamental challenge in transient stability analysis of power systems, primarily due to the highly nonlinear and complex dynamic behavior of multimachine networks. Existing methods based on the loss of synchronism (LOS) condition often require intensive numerical iterations and may ...

Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.Fault current limiters (FCLs) are essential components in modern power systems for critical protection against the damaging effects of fault currents. With extensive short circuits, routine electrical faults, and an increasing risk of failure due to unprecedented events, the development of different types of FCL has gained attention.

Conceptual design of an SFCL by use of BSCCO wire
Journal of Physics: Conference Series, 2008 Superconducting fault current limiters (SFCLs) are promising devices to reduce the fault current constraint when designing and operating power systems. SFCLs must meet requirements for precise operation, operating impedance, recovery time, and so on. SFCLs using YBCO thin film or bulk BSCCO meet some of these requirements.

Modeling the limiting performance of resistive superconductor fault current limiters for 2G HTS tape
Firat University Journal of Experimental and Computational Engineering, 2022 Fault currents in power systems force valuable power system elements thermally, electro-dynamically and electromagnetically. Due to the increase in fault current levels, the installation of components resistant to fault currents and the damage of these ...

Journal of Geophysical Research: Biogeosciences, Volume 129, Issue 10, October 2024.Abstract The globally increasing reactive N richness affects even remote ecosystems such as the tropical montane forests in Ecuador. We tested whether the δ15N values of total dissolved N (TDN), measured directly in solution with a TOC‐IRMS, can be used to help elucidate N sources and sinks along the water path and thus might be suitable for ecosystem ...
